Possible revision #1
For the proposed new 7.1.2 instruction, the presence of the word "changes" in the heading is not justified by the content of the instruction. If the instruction is not recast, the heading should read something like "Applicability of Content Characteristics" (paralleling the phrasing in RDA 1.10.5). If this change is made, the index would have to change accordingly.

Because LC's proposal comes out of a much more specific need than what can be contained in possible revision #1, I think that possible revision #2 is a better solution.

Possible revision #2
For clarity (?!), I recommend adding "providing information" to 7.29.2.1, to parallel the equivalent instruction in 3.22. This would make the scope statement:
A note on changes in content is a note providing information on changes in content characteristics that occur in subsequent issues or parts of a resource issued in successive parts or between iterations of an integrating resource.
